Ok, last year i attended a dyno day at a friends shop. I put down 222.4 after 4 runs with a variation of +/- 1.5 on either end. now this year I went to the same dyno day, same dyno and operator, outside temps were about the same. I only made 201.1 . Now last year I was only running intake and test pipe. This year I have intake, TP, invidia dual, comp stg 2 clutch and fidanza 8 lb flywheel. Can the power loss be attributed to the flywheel? I know that the torque will be affected but power? All this is kind of a moot point as I'm gonna tear the motor down for a rebuild anyway with a new setup. So what do you guys think caused this?

 

last time, fresh oil change? Barometric pressure makes a difference too. The exhaust may have lost you some power too Jeff. I highly doubt the flywheel made a change though

 

my money is on invidia dual. I dropped HP going from HKS hi-power to invidia duals ....... Lots of variables, lots of modifiers... the dyno could have large amounts of variance too.

too many variables to even begin a decent guess

 

Considering the amount if smoke that I ingested behind u on the dragon and the skyline drive........
